SPRING-GUARD FOR EYEGLASSES.

SPECIFICATION for'niing part of Letters Patent No. 650,721, dated May29, 1900.

Application filed April 14, 1900. Serial No. 12,794. (No model.)

To all whom it may concern.-

Be it known that I, ADELABD HUFAULT, a citizen of the Dominion ofCanada, residing at Southbridge, in the county of Worcester and State ofMassachusetts, have invented a new and useful Improvement inSpring-Guard Eyeglasses, of which the following, together with theaccompanying drawings, is a specification sufticiently full, clear, andexact to enable persons skilled in the art to which this inventionappertains to make and use the same.

My invention consists in a hanger of the peculiar construction shown andin its combination with the guard, the spring, and the eye-frameposts,as illustrated in the drawingswherein-- Figure 1 represents afront view of an eyeglass-frame embodying my improvement. Fig. 2represents, on an enlarged scale, a sectional View of one of the guardsand hangers, showing the construction in detail. Fig. 3 represents a topview of the same, and Fig. 4 represents the blank or form of the hangerseparate from other parts.

Referring to the drawings, A indicates the eye-frames, having the postsB fixed thereon. 0 indicates the spring, and D D indicate thespring-guards, attached at their lower ends to lugs a, fixed on therespective eye-frames. All of the above-indicated parts are of wellknownconstruction.

The spring-guard is provided at its movable end with anoutwardly-projecting top portion d longitudinally slotted, as at 2.

My improved hanger F is composed of an upper plate portion 3 and lowerplate portion 5, laid approximately parallel to each other with anintervening space or guideway G, within which the slotted top 61 of theguard slides. The two portions 3 and 5 of the hanger are integrallyunited by a narrow loop bend 6, that passes through the slot 2 of theguardtop d, and said upper and lower plate portions both extend into thehead of the post B, where they are secured, with the end of the spring 0embraced between them, by means of the screw I, which passes through theupper part 3 of the hanger, through the spring end, and through thelower plate portion 5 of the hanger and screws into the post B, as bestshown in Fig. 2.

The hanger F is made from a blank (see Fig. 4) of straight fiat Wirestock, its central part laterally reduced by impressed side recesses 7to form the narrow neck 6, and holes 8 are formed through its two ends,as indicated. This prepared blank is then folded together uniformly,with the fold-loop at the narrow neck portion and the two plate portions3 and 5 laid parallel to each other, with the space G intervening. Theseveral parts are then assembled by passing one end of the hangerthrough the slot 2 in the guardtop 01, turning its slot on the loop bend6, so as to bring the guard-top '01 into the space Gr between thehanger-plates. The end of the lower plate 5 of the hanger F is thenseated in the post B, the end of the spring 0 inserted between theplates 5 and 3, and the screw I inserted and tightened, uniting theparts as illustrated and above described. 7

As advantages attained by my invention it may be noted that by theimprovement set forth I produce a spring guard eyeglass- -frame whereinthe hanger F protects the guard-top d,while permitting the properyielding action of the guards. The hanger being integrally formed withan upper part 3 and lower part 5, which are both rigidly secured in thepost B, is compact and very efiicient and rigid and prevents the slottedtop of the guard from becoming bent or twisted, (a common annoyance withthe ordinary constructions,) while it gives a smooth exterior and neatfinish, also doing away with hook points or projections liable to catchin the clothing or when inserting or removing the eyeglasses into orfrom a pocket or case. The hanger being more rigid, the eyeglasses areless shaky on the nose and the hanger and guards are less liable tobecome displaced and the glasses broken than are those having the usualconstruction. Also for gold-filled work the improvement is desirable, asthe construction offers no exposure by cut edges of the interior metalof the gold-filled plate or stock. It will be understood that I do notbroadly claim a spring-guard for an eyeglass-frame. What I claim as ofmy invention, and desire to secure by Letters Patent, is

1. In spring-guard eyeglasses, the hanger F consisting of a single pieceof fiat wire stock laterally reduced at its 1nid-length and folded atits reduced neck, forming two approximately-parallel portions 3 and5,disposed with a narrow intervening space G, the upper and lowerportions of said hanger both extending into the post, and the ends thereseated and rigidly secured, for the purpose set forth.

2. In a spring-guard eyeglass, in combination with the eye-frame posts,the spring, and spring-guards each havingits lower end connected to theeye-frame and its upper end provided with a longitudinally-slotted top;the hangers respectively comprising upper and lower plate portionsdisposed with intervening space for the reception of the guardtop andunited by a loop-bend that passes through the slot in said guard top,the outer ends of said upper and lower portions of the hanger beingperforated and both secured in the eye-post, with the end of the springinterposed between them, bya fastening-screw ADELARD IHJ'FAU L'l.
